[0001] The present invention relates to the technical field of electrical testing devices, and in particular to an unmanned aerial vehicle electrical testing device for a power distribution line. Background Art

[0002] Testing distribution lines is a crucial step in ensuring the safety of power equipment and lines. The primary purpose of testing is to confirm whether the line is live to avoid electric shock during maintenance and repair. In some cases, it can also provide a rough estimate of the amount of power being carried. Common methods include manual testing on towers or drone-mounted testing equipment.

[0003] For example, Chinese patent application CN114062722B discloses a drone electroscope, which includes a drone with a lightweight plastic mesh box installed on the drone. The lightweight plastic mesh box is a box structure composed of lightweight plastic rods. The drone is arranged inside the lightweight plastic mesh box, the bottom of the drone is connected to the electroscope body, the test end of the electroscope body is connected to the detection end of the electroscope, and the bottom of the lightweight plastic mesh box is connected to an auxiliary electroscope guide device.

[0004] However, in order to test the electrical status of multiple cables, this drone-mounted tester needs to control the drone to accurately drive the tester into contact with each cable. The operation is complicated, and it can only test the cables in the same position at a time, making it difficult to accurately verify the electrical status.

[0005] Based on this, the present invention designs a drone electrical testing device for distribution lines to solve the above problems. Summary of the Invention

[0029] Embodiment 1: In some embodiments, referring to Figures 1 - 8 of the accompanying drawings of the specification, a drone electroscope for distribution lines includes a carrier assembly 1, and also includes a mobile multi-line electroscope assembly 2 and an auxiliary clamping assembly 3; The lower end of the carrier assembly 1 is connected to the auxiliary clamping assembly 3; The mobile multi-line electrical test assembly 2 includes a moving part 21 for moving along the cable and a lifting electrical test part 22 for performing electrical tests on multiple cables respectively. The lifting electrical test part 22 is installed on the moving part 21, and the auxiliary clamping assembly 3 is installed on the moving part 21.

[0030] When the distribution line drone electrical testing device is in normal use, the carrying component 1 drives the hanging component 31 to move, and the hanging component 31 drives the clamping component 32, the moving component 21 and the lifting electrical testing component 22 to move in turn, and the moving component 21 is placed on the cable. The carrying component 1 is separated from the hanging component 31. At the same time, the clamping component 32 automatically clamps the cable to assist the moving component 21 in moving.

When it moves to the specified position, the lifting electrical testing component 22 is started to perform electrical testing on multiple cables separately. Through the setting of the moving component 21, the lifting electrical testing component 22 can be driven to move freely on the cable. At the same time, the lifting electrical testing component 22 can perform electrical testing on multiple cables at the same position separately, and cooperate to realize multi-line electrical testing operations at different positions, improve the electrical testing effect and accuracy, and reduce the workload of electrical testing.

[0031] Embodiment 2: In some embodiments, as Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, as a preferred embodiment of the present invention, the moving component 21 includes a mounting frame 211, a rotating shaft 212, a concave roller 213, a transmission structure 214 and a driving structure 215. Two rotating shafts 212 are symmetrically arranged on the left and right. The two rotating shafts 212 are rotatably mounted on the mounting frame 211. The front and rear ends of the rotating shafts 212 are respectively fixedly connected to a concave roller 213.

The two synchronous wheels are respectively fixedly connected concentrically with the two rotating shafts 212. The driving structure 215 includes a servo motor and two gears. The output end of the servo motor is fixedly connected to one gear, and the other gear is fixedly connected concentrically with one rotating shaft 212. The two gears are meshed.

[0033] The lifting and electrical testing component 22 includes a lifting structure and an electrical testing structure. The lifting structure is installed on the mounting frame 211, and the electrical testing structure is installed on the lifting structure.

[0034] The lifting structure includes a frame 221, a sliding rod 222, a threaded rod 223, a first motor 224, a sliding plate 225 and a fixing frame 226. The frame 221 is fixedly installed on the mounting frame 211. The sliding rod 222 and the threaded rod 223 are arranged in parallel inside the frame 221. The sliding rod 222 is fixedly connected to the frame 221 and the mounting frame 211. The threaded rod 223 is rotatably connected to the frame 221 and the mounting frame 211. The first motor 224 is fixedly installed at the upper end of the frame 221. The output end of the first motor 224 is fixedly connected to one end of the threaded rod 223. The sliding plate 225 is located inside the frame 221. The sliding plate 225 is slidably connected to the sliding rod 222 and is threadedly connected to the threaded rod 223. A fixing frame 226 is fixedly installed at the lower end of the sliding plate 225. The fixing frame 226 is connected to the power inspection structure.

[0035] The power inspection structure includes an electroscope 227 and a second motor 228. The electroscope 227 is rotatably installed inside the lower end of the fixing frame 226. The second motor 228 is fixedly installed outside the lower end of the fixing frame 226. The output end of the second motor 228 is fixedly connected to the electroscope 227. A through groove for accommodating the electroscope 227 is provided at the lower end of the fixing frame 226.

[0036] The power inspection structure further includes an alarm lamp 229. The alarm lamp 229 is fixedly installed outside the fixing frame 226. The alarm lamp 229 is electrically connected to the electroscope 227.

[0037] When the UAV power inspection device for the distribution line is in normal use, the driving structure 215 is started. The driving structure 215 drives a rotating shaft 212 to rotate. The two rotating shafts 212 rotate synchronously through the transmission structure 214. The rotating shaft 212 drives the concave roller 213 to rotate along the surface of the cable, thereby realizing the movement of the mounting frame 211. When it moves to the designated position, the first motor 224 is started. The first motor 224 drives the threaded rod 223 to rotate. The threaded rod 223 drives the sliding plate 225 to move downward along the sliding rod 222. The sliding plate 225 drives the fixing frame 226 and the electroscope 227 to move in sequence. The second motor 228 drives the electroscope 227 to rotate so that the power inspection end of the electroscope 227 contacts the cable to complete the power inspection. When the electroscope 227 detects over-high voltage or other dangerous situations, the alarm lamp 229 flashes to give an alarm. When passing through the spacer dampers, the first motor 224 is started to drive the fixing frame 226 to move upward for avoidance. By driving the lifting operation of the electroscope 227 through the first motor 224 and cooperating with the second motor 228 to drive the electroscope 227 to rotate, the separate power inspection of multiple cables is realized, which is applicable to various distribution lines, has high working efficiency. At the same time, the lifting of the fixing frame 226 is beneficial for avoiding when passing through the spacer dampers, increasing the working range.

[0038] Such as Figure 3As shown, the carrier assembly 1 includes a carrier drone 11, a boom 12, and a hook 13. The boom 12 is fixedly installed at the lower end of the carrier drone 11. The lower end of the boom 12 is rotatably connected to the hook 13. The front and rear sides of the lower end of the hook 13 are fixedly provided with hanging rods, and the hanging rods are inclined gradually outward from bottom to top. The hook 13 is connected to the auxiliary clamping assembly 3.

[0039] As Figure 1 , Figure 3 , Figure 7 and Figure 8 shown, the auxiliary clamping assembly 3 includes a hanging component 31 and a clamping component 32. The hanging component 31 includes a hanging frame 311 and a support frame 312. There are two support frames 312 symmetrically arranged left and right. The two support frames 312 are rotatably installed at the lower end of the hanging frame 311. The upper end of the hanging frame 311 is hooked to the hook 13. The lower end of the support frame 312 is connected to the clamping component 32.

[0040] There are two clamping components 32 symmetrically arranged left and right. The clamping component 32 includes a connecting frame 321, a rotating rod 322, a tension spring 323, and an auxiliary roller 324. The connecting frame 321 is fixedly installed at the upper end of the mounting frame 211. The rotating rod 322, the tension spring 323, and the auxiliary roller 324 are symmetrically arranged in the front and rear. One end of the two rotating rods 322 is in limit sliding and rotational connection with the connecting frame 321. A sliding groove for cooperating with the sliding of the rotating rod 322 is provided inside the connecting frame 321. The other end of the rotating rod 322 is rotatably connected to the auxiliary roller 324. The tension spring 323 is fixedly installed between the connecting frame 321 and the rotating rod 322. The middle parts of the outer sides of the two rotating rods 322 are rotatably connected to the support frame 312.

[0041] When the unmanned aerial vehicle (UAV) electroscope for distribution lines is in normal use, the hook 13 is hooked to the hanging frame 311, and the carrying UAV 11 is started. The carrying UAV 11 drives the hook 13, the hanging frame 311, and the support frame 312 to move in sequence through the boom 12. When the support frame 312 rises, the connecting frame 321 exerts a downward force on the rotating rod 322 under the action of gravity. The rotating rod 322 pulls the tension spring 323 to rotate along the support frame 312, and the rotating rod 322 drives the auxiliary roller 324 to move outward. After the concave roller 213 is placed on the cable, the carrying UAV 11 drives the hook 13 to disengage from the hanging frame 311. The connecting frame 321 no longer exerts a downward force on the rotating rod 322. The tension spring 323 drives the rotating rod 322 to rotate, and the rotating rod 322 drives the auxiliary roller 324 to fit the cable to assist the concave roller 213 to move. When passing through the spacer dampers, the concave roller 213 rolls over the spacer dampers. The two auxiliary rollers 324 corresponding to the same support frame 312 move outward under the action of the spacer dampers. The auxiliary rollers 324 drive the rotating rod 322 to rotate. The rotating rod 322 rotates while sliding along the connecting frame 321. One support frame 312 moves upward, and the hanging frame 311 rotates with the support frame 312. The auxiliary rollers 324 corresponding to the two support frames 312 pass through the spacer dampers in sequence. There are always two auxiliary rollers 324 in contact with the cable, maintaining the stability of the operation. By driving the rotating rod 322 to rotate through the tension spring 323, the auxiliary roller 324 is driven to fit the cable, ensuring the stability during the operation. Through the setting of the hanging frame 311 and the two support frames 312, when the carrying UAV 11 drives the device to lift, the mounting frame 211 under the action of gravity can drive the two rotating rods 322 to rotate, so that the two auxiliary rollers 324 move outward. With the setting of the tension spring 323, automatic clamping during installation and removal is realized. At the same time, the auxiliary rollers 324 corresponding to the two support frames 312 will pass through the spacer dampers in sequence, ensuring that there are always auxiliary rollers 324 in contact with the cable to maintain stability.

[0042] Embodiment 3: In some embodiments, as Figures 1 - 8 shown, as a preferred embodiment of the present invention, a method for using an unmanned aerial vehicle (UAV) electroscope for distribution lines includes the following steps: Step 1: Hook the hook 13 to the hanging frame 311, start the carrying UAV 11, and the carrying UAV 11 drives the hook 13, the hanging frame 311, and the support frame 312 to move in sequence through the boom 12; Step 2: When the support frame 312 rises, the connecting frame 321 exerts a downward force on the rotating rod 322 under the action of gravity. The rotating rod 322 pulls the tension spring 323 to rotate along the support frame 312, and the rotating rod 322 drives the auxiliary roller 324 to move outward; Step 3: After the concave roller 213 is placed on the cable, the carrying drone 11 drives the hook 13 to disengage from the hanging bracket 311. The connecting frame 321 no longer applies a downward force to the rotating rod 322. The tension spring 323 drives the rotating rod 322 to rotate, and the rotating rod 322 drives the auxiliary roller 324 to fit the cable to assist the concave roller 213 in moving. Step 4: Start the driving structure 215. The driving structure 215 drives one rotating shaft 212 to rotate, and the two rotating shafts 212 rotate synchronously through the transmission structure 214. The rotating shaft 212 drives the concave roller 213 to rotate along the surface of the cable, thereby realizing the movement of the mounting bracket 211. Step 5: When moving to the designated position, start the first motor 224. The first motor 224 drives the threaded rod 223 to rotate. The threaded rod 223 drives the sliding plate 225 to move downward along the sliding rod 222. The sliding plate 225 drives the fixed bracket 226 and the electroscope 227 to move in sequence. The second motor 228 drives the electroscope 227 to rotate so that the electroscoping end of the electroscope 227 contacts the cable to complete electroscoping. When the electroscope 227 detects over-high voltage or other dangerous situations, the warning light 229 flashes to give an alarm. Step 6: When passing through the spacer, start the first motor 224 to drive the fixed bracket 226 to move upward for avoidance. Step 7: The concave roller 213 rolls over the spacer. The two auxiliary rollers 324 corresponding to the same support frame 312 move outward under the action of the spacer. The auxiliary roller 324 drives the rotating rod 322 to rotate. The rotating rod 322 rotates while sliding along the connecting frame 321. One support frame 312 moves upward, and the hanging bracket 311 rotates with the support frame 312. The auxiliary rollers 324 corresponding to the two support frames 312 pass through the spacer in sequence.
